hi, unless I am mistaken, what you are looking for are procedures. ITIL deals with the processes and not the actual step.

You could start to define your server build as a task in your change management process and use it in your release management process. But how the actual server is built, depends on many factors. What type of image tool do you have? How complex are the servers? What is the standard server software configuration, etc.

If this is what you are referring to, you won't find something like that in ITIL as it does not belong to a process.
